Abstract

The time-of-flight probing of supersonic motion of ablation products or preceding shock wave was used to extract the maximum values of initial pressure and temperature. Measurements were accomplished at three laser- tissue combinations - the TEA CO₂ laser plus artery wall, and the ArF excimer laser or the Q-switched Er:YSGG laser plus pig eye cornea and gave pressures from 1 to 40 MPa and temperatures from 450 to 700 K. These data favor the thermal ablation mechanism for all three cases.
